Filed: 1988-11-08
Abstract: PURPOSE:To make a container main body a resonant body by bonding firmly and integrating an oscillating component and a case of a portable mothproof oscillator by means of an adhesives, for example, an acrylic bonding agent. CONSTITUTION:An oscillator 2 is inserted into a recessed section 4 formed by retaining a sealing component 3 or the like forming an adhesive layer or one opening section, and an acrylic bonding agent is injected therein so that the oscillating body 2 is immersed. A cover 5 is mounted before the bonding agent is solidified in the state that the peripheral edge of the cover 5 is brought into contact with the acrylic bonding agent. Then, the oscillating body 2 in the state of being immersed is bonded with a container main body 1 following solidification of the acrylic bonding agent. Subject to the temperature applied, the same is solidified in approximately 30 minutes. Thus, the container main body is turned into a resonant body to diffuse energy of frequency hated by mosquitoes in a wide range all over.

Title: Sheet reversing carrier device and image forming device
Inventor: KANEKO TAMOTSU
IPC: B65H29/58
Filed: 1997-10-15
Abstract: PROBLEM TO BE SOLVED: To surely perform a sheet reversing operation without using a reversing flapper by imparting a curl to the vicinity of the rear end of a sheet carried from a first carrier path and guiding the tip part of the sheet to which a curl is imparted from a switchback path to a second carrier path by a carrier guide. SOLUTION: The diameter of a sheet carrier roller 204a is set to be (the diameter of the sheet carrier roller 204a) = (the diameter of a switchback roller 205a) × (1.02 to 1.05). A flag 210 projects to a first carrier path and outputs an off signal. A sheet S moving on the first carrier path 201 pushes down the flag 210, advances and outputs an on signal. The sheet S starts to form a loop from a point of time when the sheet S penetrates the tip into the switchback roller 205a and loop amount becomes large as the carrying advances. When the rear end of the sheet S passes, the flag 210 recovers to the original location and outputs an off signal. Then, the switchback roller 205a reverses and performs a switchback carrier for the sheet S. Because a curl is formed at the rear end part of the sheet S, the sheet S surely advances to a second carrier path 203.

Abstract: PURPOSE:To prevent crosstalk from being generated even when a convergent lens is driven for tracking by taking out a focusing control signal by using an edge mirror and a two-divided light receiving diode. CONSTITUTION:Three 0th and + or -1st order light beams are reflected on a recording medium 12, converged on a convergent lens 10, splitted by a beam splitter 7 and narrowed down by a light receiving lens 13 and an edge mirror 19 is inserted in the almost middle of these three beams so as to straightly advance the half of the 0th order diffracted light and the +1st order diffracted light and to reflect the remained half of the 0th order diffracted light and the -1st order diffracted light on the edge mirror. The straightly advanced light and the reflected light is received by light receiving diodes 20 and 21. The focusing control signal and an information signal can be obtained by synthesizing the light receiving outputs of the respective 0th order diffracted beams or the light receiving outputs of the both 0th order diffracted beams and a tracking control signal can be obtained by differentially synthesizing the light receiving outputs of the +1st order diffracted beam and the light receiving output of the -1st order diffracted light. Thus, an optical head can be obtained without the crosstalk even when executing tracking by driving the convergent lens 10.

Title: Scalar instruction generation system
Inventor: SAGAWA MORIE
IPC: G06F9/45
Filed: 1990-10-20
Abstract: PURPOSE:To shorten the execution time of a scalar arighmetic operation by didiving a scalar part variable fetched from a vectored source into a positive and a negative so as to stack them and generating a text from the variable fetched from a positive stack. CONSTITUTION:A scalar arithmetic operation optimizing part 2 stores the positive variable among the variables of the scalar part fetched from the vectored source in a positive stacker 3 and negative variables in a negative stacker 4 as illustrated. Then, the variables are sequentially fetched from the positive stacker 3 and the negative stacker 4 by starting from the variable fetched from the stacker 3 so as to generate the text. The text is developed and a scalar instruction string is generated. Thus, the variables in the scalar part, which are fetched from the vectored source, are divided into the positive and the negative so as to stack them, and the text is generated from the variables fetched from the positive stacker. Thus, an unnecessary code inversion instruction occurring at the time of developing the text into the scalar instruction string is eliminated and the execution time of the scalar arithmetic operation can be shortened.

Title: Synchronizer

IPC: H04L27/14
Filed: 1994-10-24
Abstract: PURPOSE: To realize a synchronizer in which timing is corrected in a stable timing and in following to a large timing deviation even when the large time deviation takes place. CONSTITUTION: This synchronizer is provided with a shift register 7 storing a synchronization code word pulse at times before and after a reception time of a synchronization code word assumed by a receiver among synchronization code word pulses obtained through correlation processing at a sampling period of A/D conversion and a subtractor means 14 providing an output of a detection value of timing deviation based on a difference between synchronization code word pulses stored at both ends 8, 12 of the shift register 7. Since the synchronization code word stored around the middle of the shift register 7 whose timing is almost matched is excluded from the discrimination of timing deviation, an event of starting unstable correction in response to a detected value of timing correction with oversensitivity is prevented.

Abstract: PROBLEM TO BE SOLVED: To efficiently make waveform data of a musical sound so as to be compressed to be recorded by using a general purpose memory and also to bring the waveform of the musical sound to be generated by reading out the waveform data more near to an instint waveform.

Moreover, at the time of reproducing the waveform data, although the waveform data are compressedly recorded in the waveform memory, a waveform being extremely near to the intrinstic waveform is made so as to be generated by reproducing true intermediate waveform values from the ratio information corresponding to respective waveform sample values and by calculating the true intermediate waveform values correctly.
